This switches the kwin effect to be a declarative effect. However, for now I have retained much of the logic that exists in cpp as a QML plugin. Fixes https://invent.kde.org/plasma/plasma-mobile/-/issues/448 Also implements https://invent.kde.org/plasma/plasma-mobile/-/issues/408 now that we can access the QML api
